You all must have heard about Embedded Systems. An embedded system is a computer system with a particular defined function within a larger mechanical or electrical system. They control many devices in common use. They consume low power, are of a small size and their cost is low per-unit.
Modern embedded systems are often based on micro-controllers. A micro-controller is a small computer on a single integrated circuit which contains a processor core, memory, and programmable input and output peripherals. As Embedded system is dedicated to perform specific tasks therefore they can be optimized to reduce the size and cost of the product and increase the reliability and performance.
Almost every Electronic Gadget around us is an Embedded System, digital watches, MP3 players, Washing Machine, Security System, scanner, printer, a cellular phone, Elevators, ATM, Vendor Machines, GPS, traffic lights, Remote Control, Microwave Oven and many more.
The uses of embedded systems are virtually limitless because every day new products are introduced to the market which utilize embedded computers in a number of ways.
Embedded Systems has brought about a revolution in Science. It is also a part of a Internet of Things (IoT) – a technology in which objects, animals or people are provided with unique identifiers and the ability to transfer data over a network without requiring human-to-human or human-to-computer interaction.
Let’s make it easy for you. For Example – You are sitting in a train headed to your destination and you are alredy a fifty miles away from your home and suddenly you realise that you forgot to switch of the fan. Not to worry, you can switch it off just by clicking a button on your cellphone using this technology – The Internet of Things.
Well this is just one good thing about IoT. We can monitor Pollution Levels, we can control the intensity of street lights as per the season and weather requirements, IoT can also provide the parents with real-time information about their baby’s breathing, skin temperature, body position, and activity level on their smartphones and many other applications which can make our life easy.
We have just begun to enter a new generation of Inventions.
